Graph a linear function with these key features:
positive on (-8, /inf)
negative on (-/inf, -8)
y-intercept of 4
i really need with more problems if anyone could me, i'd be grateful.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

idk
